EXTENSlBLE MEASURING-STICK.

SPECIFICATION forming part of Letters Patent No. 510,994, dated December19, 1893. Application filed August 7, 1893. Serial No. 482,604- (Nomodel.)

To all whom it may concern:

Be it known that I, THEODORE SGHAFER, of Maroa, in the county of Maconand State of Illinois, have invented certain new and useful Improvementsin Extensible Measuring-- Sticks, of which the following is aspecification.

This invention is particularly designed for taking pants leg measures,though it may be used for other purposes, and it is embodied in thedetails of construction and combinationsof parts hereinaftersetforth andclaimed.

In the drawings forming part of this specification Figure 3 is a faceview of the device, together with dotted lines suggesting the manner ofusing it to obtain pants leg measures. Fig. 1 is an edge view, and Fig.2 is an enlarged section on broken line 2-2 in Fig. 1.

The stick 1 has the head 2 at its upper end, and the guide or keeper 3at its lower end. The stick 6 has the keeper 4 secured to its upper endand slidingly embracing stick 1. It is held slidingly in keeper 3, andits edges adjoining stick 1 are rabbeted as seen at 7 in Figs. 1 and 2.A sliding indicator 9 fits on stick 6 between keepers 3 and 4, andengages the rabbeted angles in a manner to prevent displacement. Keeper4 is provided with spring pawl 5, which engages notches in the edge ofstick 1 and holds the two sticks in any desired co-relation, and asimilar pawl, 10, on slide 9 retains such slide in any desired positionon stick 6. The ferrule 8 on the lower end of stick 6 represents theproper space between the floor and the bottom of the pants leg, and thestick is divided into inches, or other units of measurement, andnumbered in regular order from the ferrule upward. The stick 1 isconsiderably wider than stick 6, and the keepers are so constructed thatan edge of each is flush with the other. That part of the surface ofstick 1 that coincides with, or forms a continuation of, stick 6 isdivided the same asstick 6 and,beginningwith the number next higher thanthe highest number on stick 6, it is-numbered from the head 2 downwardin regular order. The opposite edge of stick 1 is graded, or divided ina manner similar to that already described, but the numbers begin withone next the head and increase downward in regular order.

In using the device to take the measure for pants legs, the head 2 isproperly and firmly placed in the crotch of the person measured, and thedevice is extended or shortened, by sliding one stick on the other,until the ferrule touches the floor, when the pawl 5 is permitted toengage a notch in stick 1 and make the adjustment permanent. Next slide9 is adjusted to show the proper knee measure, the

pawl 10 is permitted to engage the stick and the operation is completed.The entire length of the leg is read on the right side of stick 1, asthis particular stick is constructed, and the knee measure is read onthe left side; the upper edge of keeper 4 acting as an indicator in theone instance and the upper edge of slide 9, or rather a lateralextension of such slide, acting as an indicator in the other instance.

In addition to the specific use described, the device is capable of usewherever an extensible measuring stick is required.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. An extensible measure composed of two sticks, eachhaving a keeper slidingly embracing the other, and a sliding indicatoron one stick and between the keepers, substantially as set forth.

2. In extensible measures, the combination of stick 1 having head 2 andkeeper 3, stick 6 having keeper 4 and ferrule 8, and indicator 2; eachstick being held slidingly by the keeper of the other, the indicatorbeing mounted slidingly on one of the sticks between the keepers, thestick Gbeing divided and numbered from the ferrule up, and thesticklbeing divided and numbered on one side from the head down incontinuation of the numbering of stick 6, and on the other side from thehead down beginning with 1, substantially as set forth.

In testimony whereof I sign my name in the presence of two subscribingwitnesses.

WILLIAM M. Bonn, I. D. WALKER.
